摘要
目的评价智能导引装置（ROBIO）辅助CT引导下肺穿刺活检术的可行性和安全性。方法对20例患者行ROBIO辅助CT引导下肺穿刺活检术,记录操作时间、定位时间、穿刺次数、扫描次数、辐射剂量、瞄准精度以及并发症情况。结果肺活检平均操作时间为（32±8.3）min（24-50min）,平均定位时间为（13.8±4.1）min（8-27min）。20例患者成功19例,共穿刺了20次,平均穿刺次数为（1.1±0.2）次（1-2次）。平均扫描次数为（3.6±0.8）次（3-6次）,剂量长度乘积（DLP）均值为（570.5±167.8）m Gy·cm（411.5-1117.5 m Gy·cm）。20次穿刺定位中,16次瞄准精度〈5 mm,3次为5-10 mm,1次为12 mm,穿刺针瞄准精度均值为（3.7±2.2）mm（1-12mm）。20例中气胸2例,血胸1例,无严重并发症发生。结论 ROBIO辅助CT引导下肺穿刺活检术定位时间短,穿刺精确度高,并发症发生率低,是一种导引肺穿刺定位安全、有效的方法。
Objective To estimate the feasibility and safety of CT-guided percutaneous lung biopsy by using an intelligent guiding device called ROBIO. Methods A total of 20 patients underwent ROBIO-assisted CT-guided percutaneous lung biopsy. The procedure time,localization time,puncturing times,scanning times,radiation dose（ Dose-length product,DLP）,aiming accuracy,and complications were recorded. The results were analyzed. Results The mean procedure time was 32 ± 8. 3min（ range 24- 50 min）,localization time was 13. 8 ± 4. 1 min（ range 8- 23 min）,and the mean puncturing times were 1. 1 ± 0. 2（ range 1- 2）,scanning times were 3. 6 ± 0. 8（ range 3- 6）,mean DLP value was 570.5 ± 167. 8（ range 411. 5- 1117. 5） m Gy · cm. Biopsy was performed successfully in 19 of 20 patients,and totally 20 times of puncturing were carried out in 19 patients. Needle aiming accuracy was less than 5 mm in 16 punctures,5- 10 mm in 3 punctures and 12 mm in one puncture. Two patients developed pneumothorax and one developed haemothorax,and no serious puncturing-related complications occurred. Conclusion As it has short localization time,high aiming accuracy and low incidence of complications,ROBIO-assisted CT-guided percutaneous lung biopsy is an effective and safe technique.
